So most if not all of you have beeb through the whole oil changeover to Rotella. Its in mine and running great it seems to be a good and reliable oil and I can purchase it on Amazon cheaply. But I read one review from a guy who said not so great with cold starts. I plug mine in at home but if I am somewhere for days or hours not an option. I live in Alaska and the cold has begun already; any one have experience with another oil they can recommend just in case? The Penzoil Platinum? Liqui-Molly?
